Cellular Multihop Communications : Infrastructure-Based Relay Network Architecture for 4 G Wireless Systems

  title={Cellular Multihop Communications : Infrastructure-Based Relay Network Architecture for 4 G Wireless Systems},
  author={Halim Yanikomeroglu},
In cellular communications, the amount of total available resources (frequency-time plane) and the QoS requirements jointly determine the capacity per cell. And, the transmit power (especially in the reverse-link) and the propagation conditions determine the cell size. If the demand per cell happens to be (much) greater than the cell capacity, there exists a capacity shortage. Well-known solutions within the framework of the conventional cellular architecture can be used to increase the network… Expand
UMTs cellular network with relaying concept.
Wideband Code Division Multiple Access (WCDMA) is one of the technologies for third generation systems. In a CDMA system, all users interfere with each others, therefore the CDMA system isExpand
Cooperative Relaying and Resource Allocation in Future-Generation Cellular Networks
This dissertation studies the physical layer cooperative relaying technique and resource allocation schemes in the cooperative cellular networks to improve the spectrum and energy efficiency from the perspectives of downlink transmission, uplink transmission and device-to-device transmission, respectively and proposes an efficient, low-complexity suboptimal joint resource allocation algorithm.
